Intake plenum?

[dracing70]

is there any downfall to removing the top intake plenum on a duramax. to my understanding they work kind of like a boost bottle. does anybody have any input on this. i noticed that after i removed mine my throttle response was worse. or is this in my head?

The resonator? Thing on top that says 6.6? Huge thread on it over on DP.... a lot of people remove it and cap it with a 2" plumbing cap. Did it on my LLY... gonna do it to my LMM tonight I think. Some say throttle response is better, some say just more turbo noise.... but no ones really said it hurts at all.

yes i am talking about the resonator i had it off for awhile with my new turbo but have had worse throttle response i have been through every possibility and thought it might be somethin stupid and simple like this

Throttle response will suffer if you didnt cap it.

Oh crap lol.... Ya did you put a cap on it?

 

[dracing70]

yes of course it was capped i dont know how air tight it was now that i think about it though so is it better with or without?

I vote take it off, and plug it over capping it if you can

Noise always leads to the illusion/perception of performance benefit.

Any of you remember the debut of the movie "Earthquake"? LOL....Sensuround?

I plugged mine and then capped it, just because I can
